Mentions: The patient underwent right upper sleeve lobectomy and radical lymphadenectomy, theaffected lymph node being resected (Figure 2A).Histopathology of the lesion in the right lung apex revealed invasive, moderatelydifferentiated squamous cell carcinoma measuring 3.2 cm × 1.6 cm, with angiolymphaticinvasion, marked desmoplasia, necrotic foci, and scattered foci of squamousdifferentiation. Analysis of the nodule in the superior mediastinum revealed, instead oflymph node enlargement, a well-defined, benign encapsulated schwannoma (Figure 2B) without cellular atypia or necrotic areas.There were no postoperative complications, and the patient underwent chemotherapy.Screening tests performed one year later were negative for metastatic disease andrecurrence.
